Virtual and real fusion ship intelligent control system test platform

Abstract

The invention relates to a ship intelligent control system test platform with virtual and real fusion. The ship intelligent control system test platform with virtual and real fusion comprises a real navigation database, a real-time simulation system for generating a numerical twinning fused traffic scene according to data in the real navigation database, a ship simulation system for simulating a ship in the test scene, and a tested intelligent control system for controlling and simulating the ship according to the data provided by the ship simulation system. The experimental environment constructed by the ship intelligent control system test platform with virtual and real fusion disclosed by the invention comes from real data collection, which ensures the validity of the test; and the based object experimental ship and experimental process are still based on numerical simulation, which reduces the risk and cost of the test; that is, the experimental object ship is based on numerical simulation, and the experimental scene completely comes from the perception fusion of the real world.

Description

technical field [0001] The invention relates to the field of hardware-in-the-loop simulation technology, and more specifically, relates to a comprehensive test platform for intelligent assisted driving, remote driving and autonomous navigation of ships. Background technique [0002] Compared with traditional ships, smart ships are complex systems integrating environmental perception, intelligent decision-making, planning and control. The difference between them and traditional ships is not only reflected in the basic functions, but also in the control of ship operation. way. The core link of ship intelligence research and development and verification is testing. It is necessary to test the ship's intelligence on the perception and recognition of the environment, the judgment ability and decision-making ability of the control system under different channel conditions, encounter scenarios, weather and environmental factors. In order to obtain a more complete assisted driving,...

AI Technical Summary

Problems solved by technology

The development of intelligent navigation on real ships has high risks, high costs, and low efficiency. It also faces safety problems that may be caused by uncontrollable experimental conditions.

At the same time, the real ship is under the complex interference of external wind, waves, currents, and surges, and the test scenarios and results are highly random and poorly repeatable

It is difficult for virtual simulation experiments to reproduce the dynamic scene of real navigation, especially the navigation situation and mutual influence of other ships

At the same time, it is difficult to exhaustively enumerate the various scenarios of ship navigation in the real world by using the virtual simulation method, and it is difficult to achieve complete consistency with the actual channel conditions, and the reliability is doubtful
